Professor

Senior Research Scientist, Weston Observatory

Profile

My research interests are in the areas of earthquake hazard, earthquake source mechanisms, earthquake forecasting, wave propagation studies and determination of lithospheric structure.  Since 1981 I have supervised the operations of the New England Seismic Network of Weston Observatory of Boston College, which spans the six New England states and is used to detect, locate, catalog and study all earthquakes that occur in New England and vicinity. My research has focused on studying the causes and effects of earthquakes in New England and vicinity, although I have also published papers on earthquake activity in other parts of the eastern United States and Canada, California, Europe, Mexico and the southwest Pacific. I also conduct extensive research on methods for earthquake hazard computation and earthquake forecasting. These research efforts have resulted in the publication of one book and over 80 scientific papers, over 150 professional talks, and with numerous technical reports submitted to government agencies or private firms. My current and recent students have conducted research on earthquake source mechanisms, new methods for earthquake depth computations, earthquake statistics and earthquakes induced by oil and gas production..
